-
- USES
-
- Isosorbide dinitrate is a vasodilator that relaxes the muscle of the
- blood vessels, leading to an increase in the oxygen supply to the heart. It
- is used to relieve (chewable and sublingual tablets) or to prevent (oral
- tablets and capsules) angina (chest pain). The chewable and sublingual
- tablets act quickly; they can be used to relieve chest pain after it has
- begun. The oral tablets and capsules do not act quickly; they are used only
- to prevent angina attacks.
-
- TREATMENT
-
- Take the chewable or sublingual forms of this medication at the first
- sign of an angina attack. DO NOT WAIT for the attack to become severe. Then
- sit down. These tablets are absorbed more completely through the lining of
- the mouth than from the stomach. Your mouth should be empty when you take
- these tablets. Do not eat, drink, or smoke with a tablet in your mouth. If
- the pain of an attack continues, you can take another tablet after five
- minutes, and a third tablet after another five minutes. If three tablets
- provide no relief within 15 minutes, CONTACT YOUR DOCTOR IMMEDIATELY or go to
- the nearest hospital.
- The chewable tablet should be chewed for at least two minutes before
- swallowing.
- Place the sublingual tablet under the tongue or against the cheek and
- allow it to dissolve--DO NOT CHEW OR SWALLOW IT. Do not swallow until the
- drug is dissolved, and do not rinse your mouth for several minutes (this gives
- a greater opportunity for the drug to be absorbed through the lining of the
- mouth).
- The regular tablets and the sustained-release forms of this medication
- should be taken with a full glass of water on an empty stomach. The
- sustained-release forms should be swallowed whole. Breaking, crushing, or
- chewing these tablets or capsules destroys their sustained-release activity
- and possibly increases the side effects.
- If you are taking this medication on a regular schedule, try not to miss
- any doses. If you do miss a dose, take the missed dose as soon as possible,
- unless it is within two hours of the next dose (or six hours for the
- sustained-release forms). In that case, do not take the missed dose at all;
- return to your regular dosing schedule. Do not double the next dose.
- Some doctors may recommend using this medication to prevent an anginal
- attack before expected physical or emotional stress. Discuss this with your
- doctor.
-
- SIDE EFFECTS
-
- Minor.
-
- Dizziness, flushing, headache, light-headedness, nausea, or vomiting.
- These side effects should disappear as your body adjusts to the medication.
- If you feel dizzy or light-headed, sit or lie down for a while; get up
- slowly from a sitting or reclining position, and be careful on stairs. To
- avoid dizziness or light-headedness when you stand, contract and relax the
- muscles of your legs for a few moments before rising. Do this by pushing one
- foot against the floor while raising the other foot slightly, alternating feet
- so that you are "pumping" your legs in a pedaling motion.
- Acetaminophen may help relieve headaches caused by this medication.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- fainting spells, palpitations, rash, restlessness, sweating, or unusual
- weakness.
-
- INTERACTIONS
-
- Isosorbide dinitrate can interact with other types of drugs:
- 1. Isosorbide dinitrate, in combination with alcohol, can lead to
- dizziness and fainting.
- 2. Over-the-counter (nonprescription) sinus, allergy, cough, cold,
- asthma, and diet products can block the antiangina effects of isosorbide
- dinitrate.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of those listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to isosorbide dinitrate or to any other
- nitrate-containing drugs (such as nitroglycerin).
- * Before starting to take this medication, tell your doctor if you have
- ever had severe anemia, glaucoma, a heart attack, or thyroid disease.
- * Before using this medication to relieve chest pain, be certain that the
- pain arises from the heart and is not due to a muscle spasm or to indigestion.
- If your chest pain is not relieved by use of this drug, or if pain arises from
- a different location or differs in severity, CONSULT YOUR DOCTOR IMMEDIATELY.
- * If this drug makes you dizzy or light-headed, do not take part in any
- activity that requires alertness, such as driving a car or operating
- potentially dangerous machinery.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking this medication.
- * Tolerance to this medication may develop. If the drug begins to lose
- its effectiveness, contact your doctor.
- * Isosorbide dinitrate should not be discontinued unless you first
- consult your doctor. Stopping the drug abruptly may lead to further chest
- pain. Your doctor may, therefore, want to decrease your dosage gradually.
- * If you have frequent diarrhea, you may not be absorbing the
- sustained-release form of this medication. Discuss this with your doctor.
- * Be sure to tell your doctor if you are pregnant. Although this drug
- appears to be safe, extensive studies in pregnant women have not been
- conducted. Also, tell your doctor if you are breast-feeding an infant. It is
- not known whether isosorbide dinitrate passes into breast milk.
